sPECIFIGATION forming part of Application filed March 2, 1908.

0 ail whom it may concert 1 Be it known that I, JOSEPH ARANYI, a citizenof the United States, residing at Brooklyn, in the county of Kings andState of New York, have invented certain Improvements in Apparatus forMaking and Ornamenting Bracelets, Rings, and Similar Articles, of whichthe following is a specification.

The object of the invention is to provide a machine which shall besimple and durable in operation for making or ornamenting, or bothmaking and ornamenting, annular articles-such, for instance, asbracelets, finger and napkin rings, &(3.--0f any suitable material.Heretofore it has been largely the custom to manufacture these fromstrips of metal, the ends of which were after the oruamenting operationjoined by solder. Such operation has been commonly performed by means ofa concave ornamented die, into which the metal has been pressed. Theornamentation thus produced has been very imperfect, particularly whereit has been sought to impress a deep or hold design into the article orwhere a portion of such design has been deep and another portionshallow. In addition it has been found impossible to so join the ends ofthe strip as to make the junction permanently invisible.

Under the present invention the difficulties above referred to, as wellas many others, are entirely avoided, perfect and artistically-engravedwork being produced by a simple and rapid operation, whereby the cost ofproduction is minimized. I employ an annular die, the engraved orotherwise ornamented portion whereof is formed in concave in theinternal surface. This die is sectional-i. e., in two or more parts-andthe sections are held in position by a retaining-ring fitting snuglyaround the exterior thereof. A pressure-roller of less diameter than theopening in the die extends through such opening, such roller and diebeing adjustable relatively to each other. The material to be operatedupon is preferably cut from a section of tubing, and is thereforeannular. This is placed around the pressure-roller and in line with theengraved portion of the die. Power may then be applied either to the dieor to the roller, or to both. Excellent results may be Letters PatentNo. 745,555, dated December 1, 1903.

obtained by applyingthe power to the die, the pressure-roller being soadjusted relatively thereto as to force the annulus carried thereby intothe concave engraved portion of the die, so as to reproduce theornamentation upon the exterior of the annulus or to give other form orconfiguration thereto, or both. The adjacent surfaces of the annulus andengraved portion of the die are brought together as many times asdesired to produce the best reproduction of the ornamentation. Theinvention is illustrated in the accom panying drawings, in which- Figurel is an elevation illustrating an embodimentof my invention; and Figs. 2and 3,

enlarged sectional detail views illustrating the pressure-roller, theannulus thereon, the die, and retaining-ring.

Referring to the drawings, in which similar letters denote correspondingparts, and in which I have attempted to do no more than illustrate amechanism by'which the invention may be practiced with advantageousresults, Adesignates a U-shaped supporting-frame provided withafriction-roll a, mounted upon a shaft a, supported in suitable journalsa in the frame and provided with a gear or pulley a by means of whichpower may be applied.

B designates the pressure-roller, the ends of which are mounted injournal-boxes 6, carried in vertical slots in the supporting-frame A. Ifdesired, the central portion 5' of the pressure-roller may be ofsomewhat greater diameter than the portions on either side thereof.

0 O designate sleeves in which thepressure-roller B rotates. Goactingwith these are adjusting-screws c a, passing through the upperhorizontal portion of the frame A and provided at their ends with gearsc c, actuated by a gear 0 carried by a shaft 0 mounted also in saidframe and provided with a hand-wheel 0 Obviously movement of the latterin one or the other direction will operate through the mechanism justdescribed to raise or lower the pressure-roller B.

D designates the die, the interior of which is provided with theconcavity dywhich may, if desired, be suitably ornamented in cameo.

Said die is here shown as made in two sec tions (1, held together by theretaining-ring E, fitting snugly around said sections and in suchposition as to be revolved, with its inclosed sections, by thefriction-roll a.

F designates the work. This, as heretofore stated, is an annulus of anysuitable material. It is slipped over the pressure-roller B to the pointopposite the concavity d of the die, as clearly illustrated in Fig. 3.Power is then applied to the friction-roll a, and by means of thehand-wheel c roller depressed until the retaining-ring E is brought intocontact with said roll, so as to be rotated thereby. Further downwardadjustment of the pressure-roller B forces the work F into the concavityd and effects the transfer to the former from the latter of theconfiguration and ornamentation of said concavity. Thus by a simple andrapid operation the entire process of forming and ornamenting theannulus is completed, but slight finishing being required-as, forinstance, smoothing the edges.

I have not deemed it necessary to illustrate and describe herein certaindetails which may or may not be employed in the mechanism hereindisclosed as desired by the builder or operator and which will readilysuggest themselves and their functions.

the pressure What I claim, and desire to secure by Letters Patent, is asfollows:

1. The combination with an annular die, of a pressure-roller of-uniformdiameter extending entirely through said die and supported at both ends,and means for operating said roller in a single axial plane,substantially as set forth.

2. The combination with an annular sectional die and locking mechanismtherefor, of a pressure-roller of uniform diameter extending entirelythrough said die and supported at both ends, and means for operatingsaid roller in a single axial plane, substantially as set forth.

3. The combination with a sectional annular die and locking mechanismtherefor, of a concavity in the internal face of said die, a

pressure-roller of uniform diameter located Within said die andsupported at both ends, and means for varying the relation of said dieand roller, substantially as set forth.

This specification signed and witnessed this 24th day of February, 1903.

JOSEPH ARANYI.
